Title: Water cooling device
Inventor: NAITO SHIZUO
IPC: F25D7/00
Filed: 1990-07-31
Abstract: PURPOSE:To simplify configuration of water cooling device to reduce its cost and at the same time to prevent occurrence of environmental pollution by a method wherein a porous pipe is stored in a vacuum container and a spacing capable of storing water to which water of normal temperature is formed between both circumferential walls and then an interior part of the porous pipe is reduced in its pressure by a vacuum pump. CONSTITUTION:A cylindrical porous pipe 2 stored in a vacuum container 1 is composed of ceramic pipe material having countless fine holes. Water of normal temperature is supplied into a clearance 3 within a vacuum container from a water supplying pipe 5. The water of normal temperature is flowed down in a helical form along a flow regulating plate 4 and then stored in the clearance 3. At this time, an interior part of the porous pipe 2 is reduced in its pressure under operation of the vacuum pump 12 and water is squeezed out of the circumferential wall. Water squeezed out into the porous pipe 2 is gasified at a certain pressure or less, its gasification heat is sucked and discharged by the vacuum pump 12, thereby the water remaining in the clearance 3 becomes cooled water.

Title: Flow rate control nozzle
Inventor: SAITO MASAYUKI
IPC: F23N1/00
Filed: 1988-08-23
Abstract: PURPOSE:To make a stabilized injected and discharged flow rate by a method wherein a pulse current is energized in an electromagnetic coil within a plunger case inserted into a vertical through-pass hole on an axis of the electromagnetic coil and then a control valve body is reciprocated together with the electromagnetic plunger under a generated magnetic force and a resilient force of a spring. CONSTITUTION:As a pulse-like intermittent current is applied to an electromagnetic coil 10, an electromagnetic plunger 25 is displaced toward an annular magnetic pole 31 against a resilient force of a returning spring 33. A control valve 20 is similarly displaced under a resilient force of an auxiliary spring 22 to open an orifice 12. When not energized, it may return to its original position so as to perform a reciprocating movement. This reciprocating movement is performed such that at a state having a longer conduction period, the electromagnetic plunger 25 is attracted by a large magnetic force toward the annular magnetic pole 31, resulting in that the control valve 20 may increase a degree of opening against an orifice 12 and then an amount of injected atomization is increased. To the contrary, at a stage having a short conduction period, an amount of injection of atomization from the orifice 12 is decreased. With this arrangement, it is possible to keep a discharged flow rate from an orifice of a flow rate control nozzle to a predetermined value having no variation.
